Aerosol sealant, or Aeroseal, is a service that utilizes tiny particles of sticky material that are blown through your duct system and attach themselves to the edges of leaks. Aerosealing your ductwork is the single most time and cost effective energy efficient improvement for old and new homes alike.

How Aeroseal Duct Sealing wrks - Animated whiteboard video describes the benefits of Aeroseal duct sealing for the homeowner.

This is a short clip of the aero-seal process on the duct work. This process seals up the leaks in your metal ductwork. In this example, the system was losing about 25% of its capacity to leaks. The house was less than 25 years old and was custom made. 


This is a video of ductwork releasing air into an attic. The attic was nice and cozy on a cold winter day. The reason for the warmth in the attic is pretty apparent from this video.


How do you know if you may need Aeroseal?

  • Is the forced air delivery system (ductwork) for the heating and cooling in your home made of metal?
  • Do you have places in your home where you feel little or no air flowing through the registers?
  • Do you have a hard time controlling the temperature of your home during the summertime?
  • Do you use electric space heaters in your home during the winter?

Contact the Home Energy Detective for a home energy audit if you answer yes to any of these questions.
